The actress has joined the campaign, which hopes to fix the “pet overpopulation crisis” by selling t-shirts and underwear.

The ad campaign delivers a finny take on the serious issue and features one of Heigl’s dogs, and her husband, musician Josh Kelley.

“Unfortunately I can’t cut the nuts off human men — yet,” Heigl, 33, quips in the video. “So I’ve dedicated my time to the neutering of dogs because that’s legal.”

“Launching this campaign is hopefully the type of out-of-the-box thinking we need to heighten awareness of the devastating problem, and sound the alarm that we can save many lives by simply spaying/neutering pets. Hate balls, fix pets, save lives. It’s just that simple,” she said in a statement.
